Modeled after the classic Caribou Boot, the Caribou Slim Boot from Sorel offers impeccable warmth in a slim, sleek design. This waterproof boot features a fully seam-sealed construction along with a microfleece lining for next to skin softness. 100g of insulation is put in place for warmth in frigid weather, and the removable, molded EVA footbed offers comfort and support. The hand crafted, waterproof vulcanized rubber shell and herringbone outsoles improve traction in wet conditions.

A: These have a more mid-weight insulation and the regular caribou has a heavier weight insulation. The Slim model is a great go to for milder temps but for the bitter cold you may want the regular caribou.
